    . How to identify gold jewelry and brass jewelry. Compared with brass, gold has a strong sense of heavyness. It is oppressed in the palm of the palm, because the proportion of gold is 19.32g / cm3, and the proportion of brass is only 8.9g / cm3. The yellowish the color of the gold, the better the color, and if it is red, the copper impurities are high; if it is white, the silver impurities are high, and the golden color of its gold is low.

    . How to identify K gold jewelry and foot gold jewelry. Differential K gold and foot gold are mainly hardened and elastic. The hardness of K gold is harder than the foot gold, the more pure the foot gold, the soft, and the teeth can bite the traces, while the K gold does not work. The K gold ring falls on the ground and has a strong rebellion, and the foot gold ring falls on the ground without this effect.

    . How to identify gold -plated jewelry and real gold jewelry. The jewelry made of brass materials, plated a thin layer of gold on the surface, is very low in value because its material is hard and difficult to impersonate gold, but some people sell it as 18K gold. Also under "18kgp". The color of this gold -plated jewelry is different from the color of the real gold, which is obviously reddish, lacks golden colors, and the appearance can be different.

    . How to identify nickel jewelry and platinum jewelry. Metal nickel is a material for making one yuan coin. It is white, does not oxidize, and looks like the color of platinum material, but the proportion of the two is different. CM3 is significantly different.

    . How to identify silver jewelry and platinum jewelry. Although the color of silver and platinum is similar, it is also easy to identify. The proportion of silver is 10.5g / cm3, only 1/2 of platinum. In addition, the sterling silver is soft and easy to oxidize. It will turn black after a period of time in the air, while the platinum is different, which is harder and does not oxidize.
